AGETYLENE-GAS LAMP.

Application filed April 23,

of this general character with novel and improved means for controlling the regulation of discharge of water from the reser voir to the carbid chamber or container.

It is also an object ofthe invention to provide a device of this general character wherein the valve stem at its discharge end portion has co-acting therewith a strainingelement in order to preventthe stem from becoming clogged or otherwise obstructed. The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved acetylene-gas lamp whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advanta geous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:

Figure 1 is a view partly in elevation and partly in vertical section illustrating a acetylenegas lamp constructed in accordance with an embodiment of my invention; and

Fig. 2 is an enlarged fragmentary view of the valve and its concomitant parts as ierein embodied.

Fig. 3 is a fragmentary view in elevation substantially at right-angles to that shown in Fig. 1, illustrating a means for maintaining the stem in its retracted or outer position.

As disclosed in the accompanying drawings C denotes a carbid container or chamber upon which is mounted the reservoir 3. The bottom 1 of the chamber C at its axial center is provided with an rip-standing sleeve 2 having its lower portion provided Specification of Letters Patent. Patented Aug. 24:, 1920.

1919. Serial No. 292,111.

with the perforations 4E and extending within the upper end portion of the sleeve 1 is the discharge nipple or spout 5 depending from the bottom wall 6 of the reservoir and in communication with said reservoir.

The top 7 of the reservoir R at a point in alinement with the bore of the nipple or spout'o is provided with the threaded open ing 8 in which is engaged the cap or bushing 9. The bushing 9 has a portion a extending outwardly of the top 7 when in applied position and said extended portion a is provided with the diametrically opposed open end slots 10. The outer edge of said extended portion a is also provided with the opposed notches or recesses 11 arranged in a plane substantially at right-angles to the plane of the slots 10.

Slidably disposed through the bore of the bushing 9 is a stem 12provided at its inner end with a valve 14: preferably of rubber or other compressible material and which controls the flow of the water within the reservoir R through the discharge nipple or spout 5.

The stem 12 is also tubular and has slidably disposed therethrough the wire or rod 15 of a length in excess of the combined length of the nipple or nozzle 5 and the stem 12. The inner end of the wire or rod 15 is swaged or headed as at 16 in order to regulate the flow through the nipple or nozzle 5. The opposite or outer end portion of the wire or rod 15 is angularly disposed as at '17 to afford means whereby the requisite endwise movement may be conveniently imparted to the wire or rod 15. As is believed to be self-evident when the rod or wire 15 is moved outwardly to cause the swaged portion or head 16 to engage the nipple or nozzle 5, the flow of water therethrough is cut off. It will also be obvious that the flow through said nipple or nozzle 5 may be readily regulated by the endwise movement of the wire or rod 15.

The valve 14: is constantly urged toward its seat through the medium of the expansible member 18 herein disclosed as a coil spring. When it is desired to generate the gas, the stem 12 is moved outwardly to free the oppositely directed lugs or pins 19 from the slots 10 and the valve 14 is maintained in open position by imparting a partial rotation to the stem 12 to permit said lugs or pins to seat within the notches or recesses 11.

Secured at one endto the inner face of the bushing 9 is a sleeve 20 of a length to bridge the space between the top 7 and the bottom 6 of the reservoir R. The sleeve 20 surrounds the inner portion of the stem 12 and the expansible member 18 which encircles said stem. The lower portion of the sleeve 20 is provided with the annular series of minute openings 21 so that the sleeve 20 serves as a straining element. It is to be particularly noted that the openings 21 are also closed by the valve 14: when said valve is in its closed position relative to the dis-' charge nipple or nozzle 5. This closing of the openings 21 is of advantage as the possibility of water entering the sleeve 20 above the valve 14 is eliminated.

From the foregoing description, it is thought to be obvious that an acetylene-gas lampconstructed in accordance with my invention is particularly well adapted for use by reason of the COIIVGIllGIlCG'EtIlCl facility with which it may be assembled and operated and it will also be obvious that my invention is susceptible of some change and modification without departing from the principles and spirit thereof and. for this reason do not wish tobe understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice except as hereinafter.claimed.

I claim:

Alamp of the class described comprising a carbid chamber, a reservoir imposed upon the chamber and provided with a discharge nozzle extending within the chamber, a sleeve extending through the reservoir and secured to the top thereof, said sleeve eX-, tending to the bottom of the reservoir and the openings of the sleeve when the valve is in closed position with respect to the discharge nozzle. 7

In testimony whereof I hereunto affix my signature in the presence of two witnesses.

MARK LEONHARDY.
